Answer:
=615.44 m^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
= pi (14)^2
= (3.14) 14^2
=615.44 m^2
The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.
1. 4x + 3 = 3x +12
Subtract 3x from each side:
x +3 = 12
Subtract 3 from both sides:
x = 9
2. -2 + x = 2x -7
Subtract 2x from both sides:
-2 - x = -7
Add 2 to each side:
-x = -5
Multiply both sides by -1:
x = 5
Answer:
The co-ordinates of Q' is (5,2).
Step-by-step explanation:
Given:
Pre-image point
Q(-7,-6)
To find Image point Q' after following translation.
Solution:
Translation rules:
Horizontal shift:
when 
the point is translated 
units to the right.
when 
the point is translated units to the left.
Vertical shift:
when the point is translated units up.
when the point is translated units down.
Given translation shows the point is shifted 12 units to the right and 8 units up.
The point Q' can be given as:
Q'=
So, the co-ordinates of Q' is (5,2). (Answer)
Answer:
(1.5)x
Step-by-step explanation:
90 minutes = 1.5 hours therefore
if car travels x miles in 1 hour
then the care has to travel (1.5)x miles in 90 minutes
